i SHEET-DELIVERY MECHANISM FOR PRINTING-MACHINES.

To all whom it may concern:

Be it known that I, HqwAnn M. BARBER, a citizen of the United States,and a resident of tonington, in the county of New Londonand State ofConnecticut, have invented a new and useful Improvement in Sheet-Delivery Mechanism for Printing-Machines, of which the following is aspecification.

{he object of this invention is to provide novel means for deliveringsheets fiat in either one or a plurality of piles, the sheets whendelivered in a plurality of piles being arranged side by side. Y Myinvention includes means for feeding a web at a certain speed and meansfor'delivefring the sheets cut therefrom, at a higher speed;intermediate variable speed means being employed for taking the advanceedge of the Web. at the speed of the web and transferring the sheets cutfrom the web, at a higher speed, as for instance, the speed of insurlngthe opening and closing of the sevthe-sheet delivery device.

My invention also includes means for slit-i.

ting the sheets longitudinally of their travel" after they have been cutfrom the web, and means for insuring the feeding of the sheets to theslitting mechanism and the takingof the sheets by the slitting mechanismabsolutely square with the side" edges of the sheets so that the sheetswill accurately I slit;

Figure 1 represents in side elevation..so.-. much of asheet deliverymechanism for printing machines as includes my invention.

. Fig. 2 is a section taken from front to rear just inside of the nearside frame, and Fig.3 is a diagrammatic section taken from front to rearcentrally through the delivery mechanism.

A. pair of rotary cutters 1, 2 are mounted on suitable shafts 3, 4, andare herein shown as having one set of coacting bl'ades 5, 6, for cuttinga sheettran'sver'sely from the web every revolution of the cutters.Guides 7, 8, for,'the web are located below the cutters h The sheetdelivery table is denoted by 9.- A sheet delivery device is arranged tode'- posit the sheets on the table9, which delivery device is hereinshown as an endless delivery carrier 10 having sets of grippers 11thereon at suitable intervals. A slitting cylinder 12 Specification ofLetters Patent.

Application filed December 28, 1914. Serial No. 879,324.

is mounted upon a shaftl3 driven at a continuous speed, which cylinderis herein shown as provided with two sets of grippers14, 15.

provided with a set of grippers 18 arranged to transfer the sheets fromthe slitting cyl cylinder 12.

The sheets are slit longitudinally oftheir travelon the dylinder 12 intoany number of sections by providing a slitting shaft, 23, with oneormore slitting disks 24, coacting with the slitting cylinder 12. I

Suitable cam mechanisms are provided for eral sets of grippers at theproper times for the transfer of the sheets, which cam mechanisms willnot be specifically described herein as they may be of well known'orapproved construction. 7 The web is fed through the rotary cutters 1, 2,at a certain speed. The slitting cylinder 12 is driven at a highersurface'speed,

in the present instance through a train of gears 25, 26 27, 28, 29. Theendless sheet delivery carrier 10 and the transfer cylinder '16 aredriven at the same surface speed as the slittingcylinder 12, through atrain of gears 29, 30, 31, 32, 33. The cylinder 19 is i driven at avariable surfacespeed ranging from the slower speed of the web to thehigher surface speed of the'slitting cylin der 12, through the variablespeed gears 34,

35, which gears are so arranged lil -11113 the grippers 21 and 221will'be traveling at the 3 speed of the web at; the time. for grasping theadvance edge of the web and will be traveling at the increased speed ofthe grippers 14 and 15-'respectively' of the slitting cylinders at thetime the sheets cut from the web are transferred thereto.

As the longitudinal cut in the sheet is made after the sheets have beencut from the web, it is essential that the sheets be taken by theslitting cylinder perfectly square with the side edges of the sheets.

This is accomplished by the device hereinabove described, by means ofwhich the advance edge of the slower travelin web is taken at the speedof the web and t 1e sheets cut therefrom are transferred to the slittingmechanism at the speed of the slitting mechanism.

Where I have used the term cylinders, I wish to include any type ofcarrier for the sheets, and where I have referred to the term grippers,I wish to include any suitable means for engaging the sheets to leadthem through the prescribed paths.

It is evident that various changes may be resorted to in theconstruction, form and arrangement of the various parts withoutdeparting from the spirit and scope of my invention, and hence I do notwish to limit myself to the structure herein set forth, but

\Vhat I claim is:

1.
